Just got my tf50 kit today and have my results. Wondering if I should raise my CYA or not. I run an IC40 swcg in 20% output all the time and I'm happy so far.
Results:
FC 7.5
CH 140
CYA 35-40
CC 0
TA 90
PH 7.8

As you know, the general recommendation is 60-80ppm for CYA with a SWG. But, if you have little sun, then maybe you can get by fine with the lower level.
Are you then running the pump 24/7? Your FC is a little high for a CYA of 40. 20% is as low as you can go correct? You could cut back run time to lower the FC level. If you raised the CYA, it may protect more FC and allow you to cut back run time even further to save money.

Yeah I know. I don't currently have a timer though. The pool gets full sun from morning to night. I was actually afraid the fc would be a lot higher.

Pretty cheap to add a timer ... will save you more in electricity cost in just a few months.
Did you already replace your pump? Going to a 2-speed could work if you want to leave your pump on 24/7.

I'm planning to add one. Looking at the aube Honeywell digital at the moment. Thought I would give my electrician buddy a breather after getting my swcg hooked up. I wish they made a timer that would replace a standard switch that was rated for that service load. Be much cleaner looking. Not crazy about yet another grey box hanging off my house

Well after several cooler cloudier days my FC today is 12. Guess I'm going to have to get a timer on that pump or just start turning it off at night in the meantime. Doubt switching to the 3/4 hp pump will make any difference running it 24/7. They ordered the wrong pump so it will be installed this week sometime.

Even the 3/4 HP pump is significantly too large to need to be run anywhere close to 24/7.

Yes I figured that. I'm just not crazy about installing a timer at the moment

Can't the SWG be programmed to only generate for a specific time? I was under the impression they could, but now I'm wondering...

The pentair doesn't on it's own. I've heard the ones with inbuilt timers are unreliable though (the timer).
